JAMES (l. ANDREWS AND JOHN F. SUNDERLAND, OF PHILADELPHIA, PA.

STEAM-RADIATOR.

SPECIFICATION forming part of Letters Patent No. 255,071, dated March14, 1882.

Application filed November 15, 1881. (No model.)

To all whom 'it may concern Beit known that we, JAMES G. ANDREWS andJOHN F. SUNDERLAND, citizens ot' the United States,residing atPhiladelphia, in the county of Philadelphia and State ot' Pennsylvania,have invented certain new and useful Improvements in Steam-Radiators, ofwhich the following is a speeilication, reference being had therein tothe accompanying drawings.

Our invention relates to steam-radiators; and it consists in theconstruction and arrangement of its several parts, as will behereinafter fully set forth,and pointed outin theclaim.

In the 'accompanying drawings, Figure 1is a perspective of the radiator.Fig. 2 is a section cut bya horizontal plane passing through line w m.Fig. 3 is a side view of one of the joints; and Fig. 4 is an elevationot' the frontend, showing one edge of the joining plates. j

In Fig. 1 the sections Aform aradiator, which is fastened togetherbythejoints D, the whole being supported by the straps F, hanging frombrackets in the sides of the Wall or from the ceiling. The word secton'7in this sense means one of the parts A, which make up a set ofradiators, and not a section cut through some .part of the radiator. drepresents the openinginto the radiator which receives the pipe H. eisthe outlet of the radiator into the P1P@ g- In Fig. 2, d is a section ofthe passage into the radiator; f and g, the passages of the inside,formed by the thin partition lr, ruiming nearly to the back end oftheinside of the section. The opening It leads into the joints D throughs, and on into the other sections in the same Way.

Fig. 3 shows the angle at which the jointis fastened to the radiator andthe opening s, which coincides with apertures hin D, Fig. 2.

In Fig. 4 the joint D is composed of two metal plates, z z, riveted orcast to the sides of the radiator, and the packing O, fastened togetherby the bolts w w.

The notches nin the joint D, Fig. 1, may be made to more readily takeoutthe bolts if they are longer than the width ofthe sections.

When fitted for use the steam enters the radiator by the pipe H, passingthrough: d into and along the space f around the end of the ,verticalpartition k, and back to the front end and out at h, thus completing thecirculation all in the section A, and so on through the sections, andescapes at e.

One ofthe advantages of this improvement is the convenience with whichany ot' the sections ean be taken out and not disturb the others. Thesections are joined onlyin front, and the Workman, removing one, doesnot have to get in under or up behind the set to unfasten any bolts atthe back part. Another advantage is that asingle section can be nsed ormorel be added to the set it'the number used is not sufficient to do thewarming necessary. The rear ends of the sections are kept at the rightdistance apart by blocks, one of which is shown in Fig. 2 at M.

What we claim as our invention, and desire to secure by Letters Patent,is-

'Ihe combination ofthe radiators A A A, provided with centrallyarrangedpartitions lr,

joints D, consisting of the plates z z, having arms upon opposite sidesand cast to the sections A. the washers o and bolts x x, and the blocksM, said washers and blocks beingadaptedto keep the sections separate andreadily detachable from each other, as shown and described.

In testimony whereof we have affixed our signatures in presence of twowitnesses.
